Belkin DVI SOHO KVM problem in ubuntu


I am a real newbie with Linux so have fiddled as much as i can after googling for possible solutions.
I have just purchased a Belkin 4-port SOHO DVI/USB KVM, to control 1x WinXP, 1x Win7 32bit, 1xMAC OS 10.4.x server and 1x Ubuntu 10.10 64bit workstation. WinXP, Win7 and MAC OS are controlled perfectly. Ubuntu is giving me grief.
Belkin part No. F1DD104LEA - quoted in manual as working with Linux (with USB support)
Mobo - ASUS P5N-E SLI
Monitor - Samsun Synvmaster 245B LCD panel
Keyb - Razer Tarantula - RZ03-0007, MAC Mitsui USB
mouse - Logitech G5, MS intellimouse v2

PS/2 keyb MS wired keyb 500, mouse 3button logitech

OS - ubuntu 10.10 64bit workstation installed, ubuntu 9.10 64bit on CD

firstly, when i switch to each of the other 3 OSes the LED on the KVM for video is solid, on ubuntu it continually flashes - video is displayed in all 4 OSes perfectly. SHould i take it that there is something not quite right since the LED is flashing - or could it be indicating a problem with keyb/mouse/

In ubuntu no combination of my 2 USB keyboards, or USB mice let any device work, any combination in any of the other OSes work fine.
Plugging in PS/2 peripherals work fine in ubuntu.

Unplugging the USB lead from the KVM to the ubuntu box, and then plugging in separately either of the USB mice work, or the MAC USB keyb works fine - Razer tarantula keyboard only works if both of its usb leads are plugged into ubuntu box.

If i plug any combination of USB devices into the ubuntu box the USB mouse will not work.
This is replicated in live 9.10 64bit

Is this because the keyboards are USB hubs and its confusing the usb detecting application, i had thought of getting 2 usb to ps/2 connectors to hopefully get around the problem. Otherwise im out of ideas

I have got some clues from typing in dmesg into terminal ..
the last part of the output follows.
